Rascal Flatts sing about being “changed for the better” on the title-track opener of their latest. But there’s not much different about the country trio on their eighth studio album. Which isn’t such a bad thing. Working again with longtime producer Dann Huff, they turn solid craftsmanship into radio-friendly results on songs like “Come Wake Me Up,” an achingly good ballad. Elsewhere, “Hot in Here” is not a remake of the Nelly hit. Now that would be a real switch.
